Doosan established their Construction Equipment Division in 1977 and in the next year, they produced and shipped their first excavator. In the years to come, they would develop their branded SOLAR series of hydraulic excavators, produce wheel loaders, start their own hydraulic machinery and tools factory, and become one of the premier construction equipment companies in the world.  

After decades of providing reliable, innovative construction equipment, Doosan has expanded again. Rising to meet demand, the company has opened a brand new 100,000 sq. ft. distribution center right next to the Doosan Infracore North American headquarters, northeast of Atlanta, Georgia. Built with inventory growth and faster parts delivery in mind, the new location means Doosan will be able to better provide customers and dealers a wider variety of quality service options.

Partnership with DHL Supply Chain

By partnering with DHL Supply Chain, a leader in contract logistics, shipping will be reliable and prompt, leading to reduced cycle times. This means customers won’t have to wait long for critical replacement parts. In fact, most of Doosan’s parts will be included in the inventory at the new location, as well as some lower-volume parts coming in from overseas, which will help reduce shipping costs. Fast delivery (under two days) can be expected on most parts coming from the distribution center.

Director of the parts and supply chain, Clay Caldwell, is excited about the partnership for a number of reasons, not the least of which is the fact that DHL truly understands the way Doosan does business. Plus, they can “provide strategic warehousing options and seamless transportation integration.”

Commitment to Doosan Customers

Director of the parts and supply chain, Clay Caldwell, said that the new distribution center is “a signal of [their] commitment to Doosan customers in the United States and Canada.” Edward Song, CEO of Doosan Infracore North America LLC added, “Doosan is committed to being a top-five construction equipment brand in North America, and this new parts distribution center illustrates our promise to support our dealers and customers with parts availability and prompt delivery.”

Construction Parts When We Need Them

There’s definitely a clear theme: parts are available sooner and faster. That’s a win-win for everyone involved. With around 40,000 stock keeping units available to ship throughout the US and Canada, this is a big move we’re excited about in 2019.

A division of Kobe Steel and based in Houston, Texas, Kobelco Construction Machinery USA, LLC (KCMU) began manufacturing excavators in 1930. The very first short rear swing excavator was invented by Kobelco to allow  work to continue even in areas without much room to move around. This is the kind of innovation they’ve become known for, and they continue to forge new designs that make completing construction jobs easier.

Creating the Kobelco Crane Division

In 2003, Kobelco launched their crane division, which now heavily focuses on crawler cranes. Today, KCMU acts as the distribution point for Kobelco’s Lattice Boom Crawler Crane products in the western hemisphere. Now with seven models available, between 85 and 600 tons, Kobelco cranes are a leader in the crane industry, thanks to their commitment to pushing past industry standards to create stronger, more intelligent machines.

Getting to Know the Kobelco G-Series Cranes

As a leader in hydraulic lattice-boom crawler crane manufacturing, Kobelco is constantly working on improvements in both the functions, energy saving features, and ease-of-use. The line of cranes includes seven different machines that have been re-designed in nearly every way. Engines and hydraulics have improved, energy conservation has increased, and maintenance has been simplified.

Saving Energy with G-Mode

Pairing power with energy conservation has been a priority for Kobelco and G-Mode is in place to do just that. An element included in G-Mode is the energy saving winch control system. By conserving energy, maximum speed can be reached even when in low idle. Additionally, with the Auto Idle Stop feature, the engine is halted whenever the crane is stopped, also helping to minimize fuel consumption.

Cab Space in the G-Series Cranes

The newly re-designed G-Series cranes keep the operator in mind. Cab space has increased to 109.5’ from 77.34’ and each is fully enclosed. The wider door makes it much easier for operators to enter and exit, while more leg room enhances comfort. In addition, views from the G-Series cabs have gotten wider (from 10.8’ to 11.7’), boosting the efficiency and safety of the jobsite.

G-Series Upper Machinery

Upper frames of machines in the G-Series are built with all-welded alloy steel, CAD designed intelligently for the most durability and strength. The dependable wet-type disc brake system allows for quieter operation. It also uses forced oil circulation, which helps to keep the brake temperatures cool even when used for long periods. Because the system is completely sealed, its service life is extended. Again, the operator was thought of, and the brake pedal was moved lower to help cut down on fatigue when in free-fall mode.

G-Series Lower Machinery

High-tensile strength steel that’s completely welded yields stronger machines. Hydraulic travel motors that are driven independently and that include planetary reducers have

 three steering modes, which help operators more easily maneuver the machine even over rough terrain. An independent crawler drive allows for differential track speed steering and track counter-rotation for even more control.

Load Moment Indicator (LMI) Monitor

This 12” touch panel screen includes a screen protector and sunshade, allowing the crane operator to see necessary data even when the sun is beaming down. By introducing universal pictograms, the LMI helps operators work more efficiently. Important information shared includes wind speed, engine speed, over-swing prevention device, and hook height.

 

G-Series Hydraulic System

Improving the hydraulic system was imperative, as the system controls every single operation of the crane, from boom and load hoist to crawler frame installation and removal. Depending on what the job calls for, the hydraulic circuit can be a single pump or dual pump flow. The operator may choose to switch between the two as needed.

Overall Crane Maintenance

If you’re sensing a pattern here, it’s that Kobelco has simplified as much as possible. This includes maintenance. The longer your crane is in operation, the faster your job is completed and the less money you’re wasting on diagnostics and repairs.  

Crane Rentals and Sales

When looking for a crane to purchase or rent, it’s important that the dealer you choose is able to answer any questions you may have and be available for service when necessary. Our professionally trained sales and service staff can help you choose the right machine for the job and keep it running smoothly for the duration. Contact us today to get started.

 


Usually it’s lattice boom crawler cranes getting recognized when it comes to wind turbine installation, thanks to their boom lengths, considerable counterweight, and turbine strength. All of this power is needed to lift the many heavy components of a wind turbine. However, even before a lattice boom crawler crane can make it to the location where the turbine is to be assembled, heavier-duty, tougher machines are needed to haul the parts in place. That’s where the Terex RT 100US came in when IEA Constructors, Inc. needed it.

Constructing the Upstream Wind Energy Center

On rent from RTL Equipment, the Terex RT 100US was brought in to take on a project just north of Neligh, Nebraska. Eighty-one 2.5 megawatt (MW) General Electric wind turbines make up the Upstream Wind Energy Center and are in place to produce 202.5 MW of energy. That’s enough energy to supply every household in Neligh and several in the surrounding area with power.

Rough Terrain Cranes: Unsung Heroes of Wind Farms

First things first: ground preparation must take place before the turbines can get to work for the community. Rough terrain cranes were brought in to do the heaviest lifting, including laying the rebar and steel cages for the bases before concrete could be poured. This is incredibly important work and must be done correctly the first time, so that each turbine is able to withstand high winds and harsh weather, as well as the force generated by the blades themselves.

RT 100US Boasts Automatic and Manual Transmission

Crane Assembly/Disassembly Director, Roger Galloway was impressed with the RT 100’s ability to work in a tight space, while carrying out its heavy-lifting duties. “The RT 100US crane has a small footprint, which means less ground prep work and less money spent on site preparation.” Plus, manual drive is available as well as automatic, which allows the operator to have that much more control. When using automatic, the crane swiftly drives to and from tower sites. Craner operators appreciate the manual transmission when the terrain is especially difficult.

Timelines Respected with Terex

Not only did the RT 100US need to be strong enough to handle such a precise and important job, it had to do so within a strict timeline. Rebar installation mustn’t take longer than six hours and the crane had to place reinforcing rebar panels, which weighed up to 7,000 pounds each. Mike Hedrick, the crane operator on the job, said, “A typical base construction job requires roughly 25 to 30 picks to place the material. The Terex crane allows me to efficiently move the rebar panels into place and adjust the boom from 40 to 100 feet, depending on where they are needed.”

Integrating the Demag IC-1 Control System

An impressive 13,000-pound bolt cage filled with concrete sits in the middle of the rebar, creating a secure base. Thanks to the Demag IC-1 control system integration (new to the Terex RT 100US), the operator had full control. Hendrick could control the dial-down swing function and valve speeds.This allowed him to gain more accuracy, thus saving the entire project time. Galloway added that the RT 100US was actually the better choice over a 130US capacity class crane when it came time to place the cage.

Operator Settings

A bonus of the IC-1 control system is that it allows multiple opeto choose their settings. This, again, cuts down on operating time. When a new operator arrives to relieve the previous operator, they can simply choose their pre-set preferences.

Saving Time with the RT 100US

On this particular job, there were four cranes on hand and many times, one crane needs to return to the site to complete a turbine tower base. That means taking the time to prep and load a crane, transport it back to the site, unload it, and prepare it for work. With the RT 100US, it’s tough enough to withstand transportation without issue, so it can get right back to work on the project, minimizing downtime.

Buying or Renting Rough Terrain Cranes from RTL Equipment

It goes without saying we were pleased with how well the Terex RT 100US handled the extensive job IEA Constructors needed. However, we aren’t surprised. Terex has been on the leading edge of crane innovations for years. That’s why they’re one of the brands we’re proud to offer both for sale and rent. Our professional sales staff is on hand and ready to discuss which machines would work best for you and your next job.


It’s no secret to anyone that construction machinery is an expensive investment. Whether you plan to rent or outright buy a crawler crane, rough terrain crane, or any other large machinery, you are going to have to negotiate a high dollar deal. One of the hardest decisions companies have to make is whether it is a better investment for them to buy the machinery or to simply rent it for a period of time. RTL Equipment would like to provide some helpful insight to allow you to make informed decisions that will ultimately benefit your company.

Job Frequency & Project Length

The ultimate factor to take into consideration is how often you think you will be using this equipment. As a contractor, you’ll need to think logistically about the frequency of a machine’s use on a job site. For example, if you are renting a machine that is sitting at idle for long periods of time on the job site, you are throwing money away that could be put towards outright buying one. The amount of jobs you have lined up can also be a huge factor. There is no need to buy a crane if you don’t have enough jobs lined up to payback your investment in the near future.

Inventory Control

One thing that people many people do not take into consideration with owning a piece of machinery is the ‘forgotten’ costs. Things such as maintenance, hauling, and parts, and storage are expenses that add up quickly. Over the long term, buying will be an option that pays itself back far more than it would with renting, given that you have enough work to keep the machines operating. It’s also worth noting that job dates can extend, sometimes massively, depending on the weather. If you are renting, you will have a higher bill for a single job compared to a purchased item.

State of the Economy / Tax Breaks

Currently, renting is the most popular trend for contractors looking for heavy equipment. However, with the IRS Section 179 Deduction, businesses that own or lease machine equipment can write off taxes, interest, insurance, and depreciation for both new and used equipment up to $500,000 with a $2,000,000 capital purchase limit. Considering that cranes and trucks are such a hefty investment, current policies like this are bringing back consumer confidence in buying compared to renting. If you are looking to buy or lease, consider reading into more about Section 179 and other benefits available for you.

Crane Rental and Sales Distributor

RTL Equipment is based out of Iowa and has been selling, leasing, and renting heavy equipment machinery to companies around the United States since 1989. If you are looking for hydraulic excavators, hydraulic crawlers, truck cranes, rough terrain cranes, all-terrain cranes, lattice boom crawlers, or anything else from our diverse inventory, give us a call! We sell and rent equipment from big names like Terex, Kobelco, Tadano, Mantis, Doosan, and many more.

RTL Equipment Rents Crane to IEA

We’re pleased that IEA Construction  is currently renting a Terex RT-100 from us. The RT-100 is a powerhouse, with a main boom length of 174 feet (53 meters) and maximum boom length of just over 223 feet (68 meters). With its exceptional maneuverability and hydraulics, the RT-100 can navigate wind lay-down yards with ease. Plus, its serviceability makes it ideal for use in wind farm construction, when the operators will likely be miles away from a town. The boom wear pads are easily adjusted and their replacement is simple, because the boom doesn’t need to be taken apart to do so. Plus, the majority of the fluid levels can be checked at ground level.

On June 12, 2018, the Iowa Transport Commission will decide whether a proposed five-year plan to spend $3.4 billion on highway construction moves forward. This proposal comes after several years of working to reduce the number of structurally deficient bridges on state highways. From 2006 to 2017, the amount of defective bridges went from 256 to 51, according to the Iowa Department of Transportation. A continued focus on improving Iowa roadways has lead to the 2019-2023 fiscal year plan.

Iowa Transportation Improvement Program

In May, the Iowa Department of Transportation came out with their proposal for 2019-2023. This five-year agenda outlined plans to not only repair faulty roadways, but to also invest in railroads, trails, aviation, and more. The idea is to modernize transportation services to make them safer for the public. Over half of the proposed $3.4 billion would be earmarked for improving the existing Iowa highways. Additionally, the plan would set aside over half of the budget to focus on rural Iowa roads.

2015 Fuel Tax Led to Projects

This proposal would use 100% of the revenue generated by a state fuel tax increase that began in 2015. Prioritizing funding for infrastructure projects like this was the goal when the tax was introduced and it’s what the Iowa DOT is counting on to complete the proposed projects.

Iowa Interstate Projects

According to Stuart Anderson, the director of the Iowa DOT’s Planning, Programming, and Modal Division, the plan would also focus quite a bit on western Iowa interstate projects. For instance, the state is currently working on reconstructing interstate systems in the Council Bluffs and Sioux City areas. The interstate system in Council Bluffs, alone, carries up to 75,000 vehicles each day. Construction is taking place now to allow those roadways to withstand increased traffic.

On the eastern side of the state, the I-74 Mississippi River Bridge project is well underway. According to Danielle Mulholland, the bridge’s project manager at the Iowa DOT, has said that 45% of traffic through the Quad Cities travel over the bridge. Construction on the bridge has been a tandem project between Iowa and Illinois transportation departments.

Smaller Highway Projects

There will also be a focus on highway projects, if the proposal moves forward. The plan outlines construction on US 64 to Iowa 21 in Waterloo, Highway 30 in Nevada, and more. While larger interstate projects are mentioned, these highways are in need of upgrading and improvement as well, and safety issues would be addressed.

Supporting the Economy

Ensuring roadways are safe isn’t the only objective of this five-year highway improvement plan. Anderson has said that the program would also provide a boost to the economy, providing several opportunities for construction and equipment companies. He said that the proposal “continues to reflect the Iowa Transportation Commission’s commitment to investing in projects that support Iowa’s economy and provide safe mobility of getting you there safely, efficiently, and conveniently.”

Federal Funding for Highway Projects

Something to keep in mind is that in 2015, the Fixing America’s Surface Transportation (FAST) Act was signed into law. The five-year bill is currently generating funds by implementing changes to passport rules, through privatized tax collection, and Federal Reserve Bank dividends. This means funding of $305 billion doesn’t have to come from increased transportation user fees. Because FAST will expire on September 30, 2020, there’s uncertainty about whether the federal funding will be available afterward for highway projects.

Downtime on a jobsite can be costly. Not only are you on a schedule, but you also don’t want to pay your employees not to work. There are several ways to decrease the likelihood of downtime and damage when it comes to excavators. As always, make sure to cite your manufacturer’s manual to find the best practices for your machine.

Schedule Regular Inspections

You don’t know about problems with your excavator if you don’t perform routine inspections. Starting with a walk-around inspection, the operator should make sure there are no leaks, inspect the tracks, pay attention to the rollers, and anything else within view. Other items to pay close attention to include the rock guards, track chains, track bolts, main idlers and rollers. Remember to read the manufacturer’s operation manual and follow the proper guidelines for maintenance.

Keep the Undercarriage Clean

Excavators are working in some of the dirtiest conditions and that leads to undercarriage build up quickly. Debris can cause damage and premature wear to the equipment. When working in muddy jobsites, the water stuck in the undercarriage can lead to rust and a breakdown of the components. In colder climates, the debris can freeze, causing damage to bolts, rollers, and other areas of the track. Plus, this debris can carry quite a weight. That added weight can lead to more fuel being used than necessary. Don’t let dirt lead to costly problems—clean out your excavator undercarriage regularly!

Pay Attention to Track Tension

When track tension is ignored, it can lead to damage and downtime. If a track is too loose, you may experience de-tracking. Tracks that are too tight can lead to loss of power. In fact, tracks that are over-tightened can stretch and tear rubber tracks and cause serious damage to track rollers and idlers. Remember to cite your manufacturer’s manual to find the right tension for your machine and working conditions.

Utilize Rubber Tracks When Necessary

Steel tracks aren’t always the best choice for every jobsite. In fact, they can slow down the process when used improperly. Rubber tracks are often available on smaller models of excavators and are used when working on softer ground. Because rubber excavator tracks cause less ground disturbance than their steel counterparts, they cause less damage to grassy areas, fields, or in wet or soft ground.

Rubber excavator tracks are much more cost effective than their steel counterparts. However, they require replacement more often, because they’re not as durable. Another bonus is that they can typically allow for higher speeds to be reached, because they reduce vibration and can grip the ground better. Along with allowing the excavator to be driven faster, this reduction in vibration can also lead to a longer service life of the machine and reduced maintenance costs.

Follow Best Practices

An excavator is only as good as how it’s used. Operators should follow the manufacturer’s operation manual to minimize costly damage, which can lead to hefty downtime. Something as seemingly small as the types of turns being made when operating the excavator can actually contribute to damage.

Minimize Time on Slopes

Watching the time the excavator spends on large hills can also minimize damage to the excavator. When the equipment is being moved up or down a slope puts quite a bit of pressure on the drive motor and tracks. Here’s a tip: make sure the drive motor is facing the back of the machine as often as possible to help with maneuverability when climbing a slope.

Wide Turns Help Reduce Wear and Tear

By performing pivot turns, or counter-rotation turns, too often, excavators are more likely to experience damage leading to a shorter service life. Gradual, wide turns (even introducing more Y-turns) whenever possible, can help decrease potential problems, such as de-tracking and undue wear and tear.

Avoid Edges

When encountering curbs and other steep edges or small “cliffs,” use a ramp whenever possible. Driving an excavator over these can wreak havoc on tracks (especially rubber tracks).

Pay Attention to Ground Conditions

Before sending an excavator to a new jobsite, check the ground conditions. If your machine will be better served using rubber tracks, make that change before getting to the jobsite. This will not only save time in the long run, but the machine will run more smoothly, minimizing wear and tear.

Excavator Repair Services

Our professionally trained service staff is ready to answer any questions you have about your excavator, forklift, or crane. We also offer emergency services to help you get back up and running. RTL Equipment knows your construction equipment needs to work so you can work, so give us a call to discuss how we can best serve you in the future.


In December 2017, Kobelco Cranes announced their plans for a 300/350 ton crawler crane. The standard crane’s max capacity is 300 tons and 350 metric tons with the Super Heavy Lift (SHL) specification. Recently, the first two units of the new CKS3000 lattice boom crawler crane was delivered to Guna Teguh Abadi Construction, based in Indonesia. The handover ceremony took place at the Kobelco factory in Japan and this brand new crane will get to work in April.

Executive officer of Kobelco, Shinsuke Izumi, commented “the CKS3000 is the largest model in Kobelco’s multi-purpose crawler crane lineup while also offering large-sized model features as well. The business relationship between GTA Construction and Kobelco has been growing over the past 20 years and we look forward to a continuing business relationship.”

Kobelco Boom Specs

The standard Kobelco model crane boasts a whopping 295 feet and a maximum 255 feet combination. It also carries a 98-foot mixed jib and can take on capacities of nearly 190 tons with radius of 28 feet.

Crane Operator Information

Comfort and safety of the crane operator were serious considerations—as they should be. With much larger windows, the new crane offers better visibility for the crane operator. There’s also a brand new load Moment Limiter monitor with a touch screen feature that helps eliminate confusion. These new cranes are intuitive, offer ease of use, and can save you time.

Jobsite Performance

Kobelco had a goal of “achieving maximum ease of operation” with this new crane, so its undercarriage has been reinforced and enhanced to take on the toughest job sites. Their hydraulic control system has been one of the most reliable in the market for years and the latest model is benefiting from that as well. Their free-fall winch option is available, as well, which is an excellent inclusion, depending on jobsite needs.
